Solar Sails Could Reach Mars in Just 26 Days

While SpaceX is working on Starship to carry huge payloads to Mars, the fastest flight times could be accomplished with solar sails. A new paper suggests that a 1 kg payload with a 100 square meter solar sail could reach 65 km/s relative to Mars. They could blast out of the solar system going 109 km/s, and if it's first directed towards the Sun, they could reach 148 km/s, getting to the heliopause in just 4.2 years. This opens up a range of possible missions, like the outer planets, interstellar space, and the solar gravitational lens.

✨ Solo by Pixelfed

We've been secretly building a single user federated photo sharing server (based on Pixelfed), with minimal setup, and built-in import

Solo is simple, download the code, drag your photos to the media directory and open your browser

So simple, yet super smart, Solo won't get in your way, but it will impress

Launching Oct 2023

@nickmartin Acted alone? Perhaps. Was part of a republican extremist movement that includes tens or hundreds of thousands? Yes. Law enforcement doing much about it? Not really. The occasional preventative arrest. Just one drop in the ocean, when there should be a massive operation that included purging the military and law enforcement itself of similar terrorists.

Sure why not https://www.cbc.ca/player/play/2257684035907

So without wanting this to be personal at all …
there are two ways of “consuming science” … the concluded outcomes we can now buy off the shelf, and the messy process between nothing and something.

School and mass media have shaped the common image of science into the former, and very problematically so IMO.

Actual science is the latter, and is what I refer to in finding #lk99 interesting, which is not dependent on becoming a proven technology.

Oddly enough, for me the first page of search results on both Google and DuckDuckGo show perfectly reliable results. Mayo Clinic, Wikipedia, NHS etc.

OUCH. Canada has enacted laws to require big tech companies that generate ad revenue while sharing links to stories from Canadian news outlets to compensate those publications, and the response of Google and Meta is… to start removing all Canadian news links from their pages.

That means Canadian news just won’t appear in Google searches. It spells disaster for Canadian journalism, all because they asked to share the profits from their work. https://www.reuters.com/technology/google-block-news-links-canada-over-law-paying-publishers-statement-2023-06-29/ #Canada #news #Google

The failure of the Internet to deliver its promise is particularly noticeable when you hunt for repair manuals for a product from the 90s. Used to be, the information would either be there or not there, finable or unfindable.

Now, there are hundreds of algorithmically generated sites claiming to have it just because it appeared in their search logs, generating potemkin village content traps with endless paging, broken-thumbnail named-like-the-file-you-want but actually-just-ebay-photos bullshit

“We wanted to alarm the government on the international stage.”

These architects selected to represent Canada at Venice’s Biennale disrupted impressions that Canada is a well-functioning social democracy that has housing all figured out.

Did you know that many Canadian universities, including my own, are having a recruitment and retention crisis? We just can’t get people into the classrooms since the Pandemic. You know what would solve that overnight? All governments abolishing Post-Secondary tuition for all education. (and forgiving student loans for those that still have them).

Time to break away from our US-style educational hangups. No matter your age, education should be free, always.

My short story JUST OUT OF JUPITER'S REACH is available today as an ebook and an audiobook (read by Dele Ogundiran) here: https://a.co/d/c0PKEbR

What it’s about: Tornado Onwubiko is one of seven paired with living ships to research the cosmos for 20 million euros. A decade of solitary life for a lifetime of wealth. Five years into this 10-year mission comes a consolation: A temporary meetup of the seven travelers. A lot can happen in a week.

[This is set in Binti's universe.] #Africanfuturism

@chris Poilievre getting his back up over the government defending human rights for Canadians is both telling and upsetting.

@LindaCollins11 Have them implanted in men who don't want them. Then they'll see what it's like to be forced.

This article is like something straight out of 1950s. As the province burns, we have this nonsense being written about a fossil fuel project that will emit more CO2 than any single project in the history of British Columbia. Shamefully short sighted and dangerous. “Some environmental groups and First Nations” are protesting. Nice understatement..#ClimateEmergency #endfossilfuels #CANPoli #BCPoli #CoastalGasLink

I find it increasingly annoying, if not unbearable, how #Fediverse culture locks itself out of the larger Web culture of crawling and indexing everything unless some person or some server explicitly disallows. Being able to #search and find anything from huge amounts of published posts has become an essential, core part of how research, discussion, research publishing and more is being done on the web, since more than twenty years by now. It is essential for addressing the right persons. It helps greatly in finding ongoing debates, and to add to them. No, these essential tools for online discussion can not be replaced by hashtags. Show me the proper #hashtag for https://doi.org/10.1177/17470161231180449 - I hope you get my point here.
Today, as the Fediverse has brought us a decentralised infrastructure for distributing, storing and connecting online discussions, we have better means to fence out hate speech than before. The dispense of being able to search for things goes far over the top.
Quite the opposite: I fear that to keep going on like this will risk to loose what we have reached.

What Role Will NASA Play In Developing ISRU On The Moon?

The long-term goal for NASA's lunar exploration will be a research station on the Moon. It'll be too difficult to bring all the supplies from Earth, so astronauts must "live off the land" for some of their resources. During a recent meeting, NASA officials explained how in-situ resource utilization fits in with their more extensive plans for lunar exploration. Which components will NASA build, and which will they subcontract to outside suppliers?

Recently an interesting article titled "Why AI will save the world" was published by **Andreessen Horowitz**. I was skeptical before reading it but was won over.

I look at some of the key points raised by it, but also think about whether AI will save the Data ecosystem.

We've seen many existing and new data vendors use AI to provide interfaces between humans and tooling, could we see AI powered interfaces inside the stack too?
